Romans 12:19-21

Beloved, don’t be obsessed with taking revenge, but leave that to God’s righteous justice. For the Scriptures say: “Vengeance is mine, and I will repay,” says the Lord. And: If your enemy is hungry, buy him lunch! Win him over with kindness. For your surprising generosity will awaken his conscience, and God will reward you with favor. Never let evil defeat you, but defeat evil with good.
